Weapons not appearing in Xenosaga I?

I'm playing through the game using a modded PS4's PS2 emulator, specifically AOFA as to fix the other issues with the PS4's PS2 emulator. Weapons aren't appearing in my inventory, when I go to the Weapons screen in the items menu, it just says "No data." This is true for Character Weapons, Character Ammo, A.G.W.S. Weapons, and A.G.W.S. Ammo. This is not happening for accessories. I'm in the Dock Colony area, and purchasing weapons allows me to buy them but they just disappear. Same goes for downloading them from emails like the KOS-MOS's F * BSHOT. Has anyone else had this issue? I don't see it documented on any of the emulation websites. Is there a fix? Should I just pull the save data and transfer it to a normal PC emulator?
